Jim,

I do see acl applied -

access-group outside_in in interface outside

but same time i do not see any statement matching this access-group.

access-list 101 extended permit tcp any host 12.12.12.1 eq smtp

access-list inside_access_in extended permit ip any any

access-list nonat extended permit ip any 10.10.10.0 255.255.255.0

So either create this statement -

access-list outside_in extended permit tcp any host 12.12.12.1 eq smtp

or change the access group-

access-group 101 in interface outside

Thanks

Ajay
